2000 was 16 years ago, so it's important to understand that NZ is no longer the same country that you knew. I left in 2005 for the UK and can't imagine returning to NZ to live (last time I visited was 2010). Here's just a few reasons:
* I've been spoiled by UK broadband speeds and NZ just doesn't compare.
* Food is more expensive, and not of the quality that I'm now used to (fresh seafood would be the exception).
* Higher tax relative to what I pay in the UK as a contractor.
* Real estate prices are now worse than in the UK
* It's an isolated country, you can't just hop on a cheap plane and find yourself in a completely different country & culture an hour or two later.
* Purchasing power is greatly limited. In the UK I can buy virtually any obscure item that I want online and get a good price, including P+P. Not so in NZ.
* There's very little variety in the job market for software developers, few 'cool' or cutting edge companies and no startup scene worth speaking of.
* Finally, cultural experiences are extremely limited. I know I'd miss all the museums, art exhibitions, theatre, concerts, comedians, ballet, opera and so forth. One of the biggest reasons that I left was because of boredom and the UK/EU certainly alleviated that.
